    Reduction math problem

    Hi, I'm trying to solve this very simple reduction problem, but I just can't get my head around it.

    Here it goes:

    xy + x^2 / xy

    It's supposed to be reduced, and my best bet is that the solution is
    x/y but I'm not sure at all..

    Any help appreciated!

    xy + x^2 / xy

    I will assume that you mean xy + ((x^2) / xy)

    If that is the case, xy + x/y -----> x(y + (1/y)) this last one not as nice..

    Is this what you wanted? Explain please.

    xy+\frac{x^2}{xy}\Rightarrow{xy+\frac{x}{y}}

    Combining fractions we get \frac{xy^2+x}{y}=\frac{x(y^2+1)}{y}

    Ok, I won't do it the way the other ones did it

    \frac{xy+x^2}{xy}=\frac{x(y+x)}{xy}=\frac{y+x}{y}=  1+\frac xy

    You know what? You are actually probably right in guessing that is what the poster meant. Sharp eyes

    It's not me, it's you who look for complicated things

    However, I agree on one point : the OP didn't write the text clearly...
